To all whomit may concern:

,Be it known that I, HENRY S. BnEu'INo'roN, a citizen of the UnitedStates, residing at Baltimore city, and State of Maryland, have inventedcertain new and useful Improvements in Bottle-Capping Machines, of

which the following is a specification. v

My invention relates to an improvement in bottle capping machines andthe object-is to provide a simple construction for automaticallycrimping the edge of the bottle stopper around the' head at the luoulhof the i bottle and it consists in certain novel features ofconstruction and combinations of parts which will be hereinafterdescribed and pointed out in the claims.

In the accompanying drawings, Figure 1 is a section through the machineand Fig. 2 a bottom plan view looking into the spring capping jaws.

A, represents an arm broken out through the center, and arranged toslide up andl down upon a immo (not shown) ol' the machine. The outerend ot' the frame is bored as at l, the upper'end oi which bore isinternally screw-threaded at 2 and the lower end externallyscrew-threaded as at 3, a sleeve 4 being screwed to these threads 3. Thesleeve`4 is provided with au annular shoulder 5 in the lower end Of thisbore and the external 254 screw-thread 6 to which is screwed-the camring 7.

A plunger P is-yieldingly supported within' the bores of'the arm A andthe sleeve 4, it being guided and centered at the lower end by thesmaller diameter 8 of the sleeve 4, and at the upper end by the bore ofthe nut 9 which latter screws into thethreads 2 of the bore 1. The stiffspiral spring 10 bears down upon the plunger, it being held at itsuppe;` end bythe nut 9 and its tension being regulated thel'eby.- Theplunger has a die 11 at its lower end whichs adapted to engage and pressdown upon the top of the cap, to hold it in positionv on the bottle. Aplnrality'of spring jaws 12, 12depending irom a co`l1ar13 screwnponthe-threads 14 on the plunger which is adapted to receive, bend andsecureA the edge of the cap around and to a bead at the mouth of the 40bottle. Thesejaws are sufficiently yielding to permit the plunger toreceive vthe lcap and while so doing they crimp and bend thei'edge ofthe cap' downwardly after which a. further downward-motion of the arm Ai'orees.

-the cam ring against the outer edges of thespring .45 jaws 12, 12, thecam surface 15 riding down Aupon the outer edge of the jaws therebycompressing themtogether toward a common center, their inwardlyprojecting V-shaped teeth 16 serving to indent and secure Athe j edge.of the c ap to the bead. -The spring l0 is suiliciently yielding toallow additional play or movement of the arm A, sleeve 4 and cam ring 7after the plunger has reached the cap land the jaws have bent them*selves about the edge ot' the cap and given the latter its initialdownward bend, to permit the cam surface 15 to compress the jaws andforce them inwardly tO fasten the cap to the bottle neck bead.

The foregoing perfectly explains the operation and utility ol' theinvention. 1t will be observed that the I collar which carries the jawsand the cam ring, which are the parts which receive the most punishmentmay be easily removed and replaced, and in fact that the 'entiremechanism maybe easily and quickly taken apart and put together.

Slight-eli-.mges might be resorted to in the iorni and arrangement-ofthe several parts described without departing from the spirit and scopeof my invention, and hence l do not wish to limitinyseli to the exactconstruction herein set orth, ,but-:-

Having described my invention, what l claim new and dcsireto secure byLetters Patent, is zM l. in u bottle capping machine, the combinationwith a4 supporting :irm bored at one end, o, Sleeve secured to the :umund .forming n continuation ol' the bored portion of the urm, ot nplunger. and :i plurality 0L' spring jaws cnrl'ied thereby. the innerfree ends oi.' the' inws forming a cone, nud provided inwardly with Vshaped lteeth, the V shaped teeth giving' the initial bend to the edgesof the enpzls (he laitier posses thereiniou1|d u emu ring connected withthe Sleeve, embracing; the spring' jaws forcing them. inwardly toward acommon center, securing' the cap on to tho hond ou the mouth olthebottle.
